java - error in android programming -

there 2 problems in code, simple code aims has button , type passage , when push button , go next activity show text had written.

package com.example.mysecondapp;  import android.os.bundle; import android.app.activity; import android.content.dialoginterface.onclicklistener; import android.content.intent; import android.view.menu; import android.view.view; import android.widget.button; import android.widget.edittext;  public class main extends activity {          @override         public void oncreate(bundle savedinstancestate) {             super.oncreate(savedinstancestate);             setcontentview(r.layout.main);          // reference edittext         final edittext matn = (edittext) findviewbyid(r.id.edittext1);          // reference button         button d = (button) findviewbyid(r.id.button1);         d.setonclicklistener(new onclicklistener() {              @override             public void onclick(view v) {                 intent mafhoom = new intent(main.this, second.class);                 mafhoom.putextra("selectedpassage", matn.gettext().tostring());                 startactivity(mafhoom);             }          });      }  } 

as per code suggest to

you should import

import android.content.view.onclicklistener; 

instead of

import android.content.dialoginterface.onclicklistener; 

or setonclicklistener(..) like

 d.setonclicklistener(new view.onclicklistener() {          @override         public void onclick(view v) {             intent mafhoom = new intent(main.this, second.class);             mafhoom.putextra("selectedpassage", matn.gettext().tostring());             startactivity(mafhoom);         }      });
